英文文献摘要:
Quantity surcharges exist when unit prices are higher for larger packages. We hypothesize that various sizes of goods are differentiated products, and this explains some surcharges. Estimating a random-coefficients logit demand model, we examine own and cross elasticities to determine the level of differentiation between products with different size packages.
数量附加费存在时,单位价格较高的大包装。我们假设不同尺寸的商品是不同的产品,这解释了一些附加费。估计一个随机系数logit需求模型,我们检查自己和交叉弹性,以确定不同大小的包装产品之间的差异水平。
